"In addition 6 other cancer-associated genes (BRAF NRAS HRAS ERK1 ERK2 and PTEN) were also analyzed. In total four somatic mutations were identified in three out of 101 ovarian endometriotic lesions (4% 4/101) including a KRAS p.G12V a PPP2R1A p.S256F and two ARID1A nonsense mutations (p.Q403* and p.G1926*); while no mutations were identified in the remaining 7 genes (BRAF NRAS HRAS ERK1 ERK2 PTEN and PIK3CA)"xsd:string
